IMPLEMENT FOR DRIVING SCREW HOOKS AND EYES.

Specification of Letters Patent.

Patented Jan. 15, 1907.

Application filed February 17, 1906. Serial No. 301.695.

To all 1071 0111 it may concern.-

Be it known that I, WILLIAM H. VANDER- HEROI-IEN, a citizen of theUnited States, residing in Philadelphia, Pennsylvania, have inventedcertain Improvements in Implements for Driving Screw Hooks and Eyes, ofwhich the following is a specification.

The object of my invention is to provide a simple and efficient toolwhereby a screw-eye or a screw-hook can be firmly held while it is beingscrewed into position, the tool also providing for the placing of suchscrew-eyes o-r screw-hooks in places which would otherwise beinaccessible.

In the accompanying drawings, Figure 1 is a perspective View of adriving-tool for screw-hooks or screw-eyes constructed in accordancewith my invention. Fig. 2 is a view, partly in side elevation and partlyin transverse section, showing the parts in position for the insertionof a screweye into the driving-tool. Fig. 3 is a similar view showingthe parts in the position assumed by them after the screw-eye had beenlocked in position in the driving-tool. Fig. 4 is an end view of thetool with the parts in the position shown in Fig. 2. Fig. 5 is a similarview, with the parts in the position shown in Fig. 3; and Figs. 6 and 7are views similar to Figs. 3 and. 4, respectively, but illustratinganother form of the tool.

In Figs. 1 to 5 of the drawings, 1. represents a stem suitably securedto an operatinghandle 2, which may constitute part of a pole or staffwhen it is desired to place the screw eye or hook in a positionotherwise inaccessible.

The stem 1 has a head 3 with a transverse slot 4 in its outer end, and.mounted upon said head, so as to be capable of rotation thereon, is aninverted cup-shaped cap 5, whichalso has a transverse slot in itsrounded outer end, the cap being retained longitudinally upon the head 3by means of pins 7, projecting from said head into segmental slots 8 inthe cap, as shown in Fig. 1, these slots 8 also serving to limit theextent of rotative movement of the cap on the head.

In order to apply the screw-eye to the implement, the cap 5 is turned tosuch position that its slot 6 is parallel with the slot 4 of the head,as shown in Figs. 2 and 4, and the eye is passed through the slot 6 andinto the slot 4, as shown in Fig. 2. The cap 5 is then turned to theextent of a quarter-turn, so as to bring its slot 6 at a right angle tothe slot 4, as shown in Figs. 3 and 5, the result being that, the eye ofthe screw is longitudinally confined within the slot 4, and byengagement with the walls of said slot is readily turned by means of thehandle 2.

After the screw-stem has been driven home the implement is readilyreleased from the eye by turning back the cap 5 until its slot 6 againregisters with the slot 4 of the head 3 and then withdrawing theimplement longitudinally until it is free from engagement with the eye.

In that form ofthe tool shown in Figs. 6 and 7 the cap 5 is secured tothe head 3, and

a rotatable continuation 3 of said head, disposed within the cap 5,engages the head of the screw hook or eye. In this case no specialmanipulation is needed in order to lock the screw hook or eye to thetool, as the first partial turn of the handle 2 after the application ofthe head of said screw hook or eye to the tool effects this result.

An instrument of the character described provides for the use of bothhands, one for supporting the instrument and the other for turning thesame, whereas when the screw eye or hook is directly manipulated onlyone hand can be used, and difficulty is frequently experienced ingetting a proper bite of the screw upon the wood at the start,especially if the wood is hard. The screw eye or hook, therefore,frequently drops from the hand in attempting to get a fresh hold uponthe same, because the partial turn originally imparted to the screw hasnot been sufiicient to insure a proper supp0rting-hold of the same uponthe wood. It will be evident that an implement of the character which Ihave devised effectually overcomes this objection.

1. In an implement for driving screw eyes or hooks, the combination of ahandle having a head and a cap, the latter having a slot elongated topermit of the passage of an eye or hook and having its interior surfacedesigned to conform to the shape of such an eye or hook, the portion ofthe head covered by the cap having an elongated recess shaped to hold ahook or eye from turning, one of the parts of the implement having aslot and the other a pin projecting into said slot and being rotatablymounted relatively to each other to permit of the slot in the cap andthe recess of the head being brought into parallelism or placed at anangle to each other, substantially as specified.

2. In an implement for driving screw eyes or hooks, the combination of ahead and cap for the end of the same, the cap being slotted forreceiving an eye or hook and the head be ing provided with an elongated,transverse recess for holding the eye or hook from turning, said headhaving its engaging portion rotatably mounted within the cap,substantially as specified.

3. In an implement for driving screw eyes or hooks, the combination of atwo-part head and a cap, the cap being slotted to receive an eye orhook, and the head having an elongated, transverse recess for holdingthe eye or hook from turning, one portion of the head being secured tothe cap, and its hook and eye engaging portion rotatably mounted withinthe cap, substantially as specified.

In testimony whereof I havesigned my name to this specification in thepresence of two subscribing witnesses.
